Brake disc/pad wear and sourcing quality

Tags: #wear · #part-number

Wear reports: Original-equipment brake discs lasted 120,000 km on one vehicle (2017 model, pre-restyle) ¹. Another owner replaced discs at 200,000 km ². A defective disc warped at only 48,000 km, damaging the pads in the process — uneven wear is a commonly reported issue ³⁴. SD4417-branded discs are recommended by the community as a quality upgrade.

Marketplace sourcing challenges: Sellers on online marketplaces (especially Ozon) sometimes misrepresent brake parts — for example, advertising Mazda GG-spec parts but shipping GH-spec parts, or mislabeling the part number on the packaging (media 29584) ⁵⁶. A common workaround: Hi-Q brand pads have no X80-specific part number listed, but the correct pad dimensions (e.g. 132.4 mm) still fit ⁷. When ordering through marketplaces, verify exact dimensions on arrival before installing. Local auto-parts shops are more reliable but may have limited stock; pre-ordering from authorized suppliers gives better quality control ⁸⁹.

Cumulative wear-part spend: One owner reports that his minimal wear-part spending (discs, pads, mounts, including a replaced front-right hub) has reached about 100,000 RUB (Oct 2026, RU market), and he still plans to keep the car for years; he attributes the wear to his driving style and rough-road use ¹⁰¹¹.
